Photos of a young Ko Yong-hui, the mother of North Korean leader Kim Jong-il's son and heir apparent Jong-un, have recently been released by a record label.
Also the mother of Kim Jong-chol and Yeo-jong, she was born in Japan in 1953 and went to the North with her family in May 1961. After graduating from Pyongyang University of Music and Dance in 1970, she became a dancer with the Mansudae Art Troupe in 1971.
One of the photos was taken for use as an album cover by Japan's Shinseki Record, ahead of Mansudae's first performance in the country in July 1973, while the other one is the jacket of an album released in the North.
Ko reportedly studied under legendary dancer Choi Seung-hee, who went North Korea in 1946 with her husband and established a dance school.
